Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electrical appliances, and particularly to an operating system. Background Art
[0002] At present, in a combined electrical appliance including a load switch and a fuse in a circuit, the closing and opening operations of the load switch are generally controlled by an operating system. For example, a three-position operating system with a tripping release disclosed in Chinese Patent Document CN207319934U. It includes an isolation output device, an isolation transmission device, an energy storage device and a tripping release device. Among them, the isolation transmission device includes an isolation transmission shaft (i.e., a closing and opening main shaft) rotatably provided on a frame, an isolation transmission crank arm (i.e., a main shaft crank arm) fixed on the closing and opening main shaft, and an isolation transmission pin fixed on the free end of the main shaft crank arm; the isolation output device includes an isolation output crank arm (i.e., a closing and opening output crank arm) rotatably provided on the closing and opening main shaft, and an isolation transmission groove is provided on the closing and opening output crank arm; the tripping release device includes a release plate, a tripping spring, a tripping shaft, a limit crank arm, and a linkage crank arm; the release plate is fixedly sleeved on the tripping shaft; the limit crank arm and the linkage crank arm are formed at two axial ends of a fastener, the fastener is sleeved on the closing and opening main shaft, and two ends of the tripping spring are respectively fixed on a base and the fastener. One end of the isolation transmission pin is linked with the linkage crank arm, and the other end is slidably arranged in the isolation transmission groove. The energy storage device is an energy storage compression spring with two ends respectively arranged on the isolation transmission pin and a grounding transmission pin.
[0003] In the above three-position operating system, when manually closing, an operator installs a handle on the closing and opening main shaft, applies a driving force in the closing direction to the closing and opening main shaft through the handle, drives the closing and opening main shaft to drive the main shaft crank arm and the isolation transmission pin to rotate synchronously in the closing direction, and acts on the energy storage device to compress the energy storage compression spring for energy storage. Since the main shaft crank arm is fixed on the closing and opening main shaft, and the isolation transmission pin connecting the energy storage compression spring is directly fixed on the free end of the main shaft crank arm, after the energy storage device is compressed past the dead point, the energy storage device instantaneously releases energy and immediately drives the isolation transmission pin to rotate to drive the closing and opening output crank arm to close instantaneously. Due to the short closing time, after closing, the operator habitually still applies a driving force in the closing direction to the closing and opening main shaft. During this closing process, the isolation transmission pin on the main shaft crank arm drives the fastener to rotate, so that the limit crank arm of the fastener is lapped on the tripping shaft, and the tripping spring is stretched for energy storage, so that the tripping mechanism restricts the closing and opening main shaft from rotating in the opening direction.
[0004] At the moment of manual closing, if a short circuit occurs in the instantaneously conducting circuit, the fuse in the circuit is blown. The ejector mechanism on the fuse immediately drives the opening tripping device to perform a tripping action. The limit toggle arm disengages from the tripping shaft, and the tripping tension spring releases energy, driving the fastener to rotate in the reverse direction. Then, the linkage toggle arm drives the isolation transmission pin to rotate, applying a driving force in the opening direction to the main shaft toggle arm and the closing and opening main shaft, and performing an opening action. However, due to the instant closing after the energy storage mechanism stores energy, the operator still applies a driving force in the closing direction to the closing and opening main shaft, and the operator cannot timely know the opening requirement. Then, the opening tripping mechanism applies a driving force in the opening direction to the closing and opening main shaft, and the operator applies a driving force in the closing direction to the closing and opening main shaft. The two driving forces are contradictory. Therefore, the closing and opening main shaft still remains in the closed state, resulting in the failure of the closing and opening output toggle arm to quickly open, and the circuit still remains in the short-circuit state, posing a safety hazard. Summary of the Invention
[0005] Therefore, the technical problem to be solved by the present invention is that in the prior art, when a short circuit occurs in the circuit after the instant of manual closing of the operating system, the opening action cannot be timely performed, the circuit still remains in the short-circuit state, and there is a safety hazard.

[0023] In the first unlocking state, when the opening / closing output crank arm rotates in the opening direction, a first abutting force in the same direction as the reset biasing force is applied to the first eccentric member by rolling friction of the first eccentric portion. Under the combined action of the first abutting force and the reset biasing force, the first eccentric portion is forced to switch from the first unlocking state to the first locking state. And the first limiting portion applies a second abutting force opposite to the reset torsion force to the second eccentric portion, forcing the second eccentric portion to switch from the initial to-be-lapped state across the non-lapped state and then to the to-be-lapped state.

[0054] The technical solution of the present invention has the following advantages:
[0055] 1. The operating system provided by the present invention includes a closing and opening main shaft, a main shaft crank arm, a closing and opening output crank arm, a first energy storage mechanism and a closing release device. The closing and opening main shaft is rotatably arranged on the frame; the main shaft crank arm is fixed on the closing and opening main shaft; the closing and opening output crank arm is rotatably sleeved on the closing and opening main shaft; the first energy storage mechanism has a first spring crank arm rotatably sleeved on the closing and opening main shaft; the first spring crank arm is arranged in linkage with the main shaft crank arm and the closing and opening output crank arm respectively; the first spring crank arm is driven in linkage by the first driving force of the main shaft crank arm, so that the first energy storage mechanism stores energy; the closing and opening output crank arm is driven in linkage by the first spring crank arm due to the release of energy of the first energy storage mechanism, and can be rotatably switched between a first tripping position and a first closing position on the frame; the closing release device has a closing release fastener movably arranged on the frame between a first locked state and a first unlocked state. In the first locked state, the closing release fastener is subject to a first blocking force that balances the acting force on the first crank arm end of the closing and opening output crank arm by the energy released by the first energy storage mechanism. In the first unlocked state, the balance of the first blocking force is revoked.
[0056] In the operating system of this structure, when the operator performs manual closing, he first applies a driving force along the closing direction to the separation and closing main shaft to drive the separation and closing main shaft to drive the main shaft crank arm to rotate in the closing direction, and then drives the first spring pin in linkage to allow the first energy storage mechanism to store energy. Since the closing release member in the closing release device is subjected to the first blocking force, the force acting on the first crank arm end of the separation and closing output crank arm by the energy released by the first energy storage mechanism is balanced, and the first energy storage mechanism cannot release energy and remains in the energy storage state, and cannot immediately drive the separation and closing output crank arm to rotate in the closing direction; at this time, the operator first cancels the driving force on the separation and closing main shaft in the closing direction, and then cancels the first blocking force, breaking the energy released by the first energy storage mechanism acting on the separation and closing output crank arm. The forces on the first crank arm end of the closing output crank arm are balanced, and the first energy storage mechanism instantly releases energy to drive the opening and closing output crank arm to perform the closing action until the opening and closing output crank arm is in the closing state; if the circuit is turned on and a short circuit occurs at the moment of closing, the fuse is burned out, and the ejector mechanism thereon drives the opening and closing main shaft to rotate in the opening direction. Because the operator has withdrawn the driving force applied to the opening and closing main shaft in the closing direction before the opening and closing output crank arm is in the closing state, the ejector mechanism can drive the opening and closing main shaft to rotate in the opening direction at this time, allowing the first energy storage mechanism to store energy, and immediately release energy to drive the opening and closing output crank arm to rotate in the opening direction, thereby realizing immediate opening, disconnecting the circuit, and improving the safety of the operating system.

First installation spaces and second installation spaces are respectively formed between the two sides of the middle partition plate 603 and the front plate 601 and the bottom plate 602. The closing module and the opening module are respectively arranged in the first installation space and the second installation space.
[0103] As Figure 14a shown, the bottom plate 602 is provided with a first chute 6021 for the first sliding pin shaft 2015 of the opening and closing output toggle arm 201 to pass through. The two ends of the first chute 6021 are respectively used as the first opening position a1 and the first closing position a2 of the opening and closing output toggle arm 201. The bottom plate 602 is provided with a second chute 6022. The second sliding pin shaft 4014 of the grounding output toggle arm 401 is arranged in the second chute 6022. The two ends of the second chute 6022 are respectively the second opening position b1 and the second closing position b2. In addition, it should be noted that the first chute and the second chute can be grooves or through holes.
[0104] II. Energy storage module 20
[0105] As Figure 1 、 Figure 2 、 Figure 10a 、 Figure 10b and Figure 11a shown, the energy storage module 20 includes an opening and closing main shaft 202, an opening and closing output toggle arm 201, a main shaft toggle arm 203 and a first energy storage mechanism. Among them, the first energy storage mechanism includes a first spring toggle arm 2041, a first spring pin 2042 and an operating spring 2043.
[0106] Among them, as Figure 3 shown, the opening and closing main shaft 202 is rotatably arranged on the front plate 601, the middle partition plate 603 and the bottom plate 602. The opening and closing output toggle arm 201 and the first spring toggle arm 2041 are rotatably sleeved on the opening and closing main shaft 202. The main shaft toggle arm 203 is fixed on the opening and closing main shaft 202. For example, the main shaft toggle arm 203 is sleeved and fixed on the opening and closing main shaft 202. The opening and closing output toggle arm 201, the main shaft toggle arm 203 and the first energy storage mechanism are all in the second installation space.
[0107] The first spring toggle arm 2041 is linked to the main shaft toggle arm 203 and the on-off output toggle arm 201 respectively; the first spring toggle arm 2041 is driven by the linkage of the first driving force of the main shaft toggle arm 203, so that the operating spring 2043 of the first energy storage mechanism stores energy; the on-off output toggle arm 201 is driven by the linkage of the first spring toggle arm 2041 due to the release of energy by the operating spring 2043 of the first energy storage mechanism, and can be rotated to switch between the first opening position a1 and the first closing position a2 on the frame 60.
[0108] Specifically, as Figure 10a and Figure 3 shown, a third chute 2031 is provided on the main shaft toggle arm 203 and a fourth chute 2014 is provided on the on-off output toggle arm 201. As Figure 7 and Figure 10b shown, the on-off output toggle arm 201 is provided with a second toggle arm end 2012 and a third toggle arm end 2013 on the same circumference, and a fourth chute 2014 is formed between the second toggle arm end 2012 and the third toggle arm end 2013 on the on-off output toggle arm 201; the first spring toggle arm 2041 has a first socket part sleeved on the on-off main shaft 202 and a free end fixed outside the first socket part and extending radially, and the first spring pin 2042 is fixed on the free end of the first spring toggle arm 2041. The two ends of the first spring pin 2042 are respectively slidably arranged in the third chute 2031 and the fourth chute 2014. For the convenience of description, the two ends of the first spring pin 2042 are expressed as the first end 20421 and the second end 20422, wherein the first end 20421 is inserted into the third chute 2031, and the second end 20422 is inserted into the fourth chute 2014.
[0109] When the operating spring 2043 is in the uncharged state, the first spring pin 2042 can slide in the fourth chute 2014 under the second driving force of the end wall at one end of the third chute 2031; when the operating spring 2043 releases the stored energy, the first spring pin 2042 slides in the third chute 2031 under the drive of the operating spring 2043, and applies a third driving force to the end wall at one end of the fourth chute 2014 to drive the on-off output toggle arm 201 to rotate. The above-mentioned third chute can be a groove or a through hole.
[0110] As Figure 6d shown, the first energy storage mechanism further includes a first spring head and a second spring head. A sleeve is formed or provided at the bottom of the first spring head 2044, the sleeve is sleeved on the connecting shaft 2045, the other end of the connecting shaft is fixed on the second spring head 404, the operating spring 2043 is sleeved outside the sleeve and the connecting shaft 2045, and its two ends respectively abut against the first spring head 2044 and the second spring head 404; the second spring head 404 is fixed on the second spring pin 403 (mentioned below) in the earthing on-off device 40.
[0111] III. Closing Module
[0112] The closing module includes a closing release device 10 and a holding mechanism. Among them, the closing release device 10 has a closing release part 104 movably arranged on the frame 60 between a first locked state and a first unlocked state. In the first locked state, the closing release part 104 is subject to a first blocking force that balances the force acting on the first arm end 2011 of the closing and opening output toggle arm 201 released by the first energy storage mechanism. In the first unlocked state, the balance of the first blocking force is revoked. The holding mechanism applies the above-mentioned first blocking force and revokes the first blocking force to the closing release part 104.
[0113] That is to say, the holding mechanism applies a first blocking force to the closing release part 104. The closing release part 104 balances the force acting on the first arm end 2011 of the closing and opening output toggle arm 201 released by the first energy storage mechanism, so that the operating spring 2043 of the first energy storage mechanism cannot immediately release energy even after passing the dead point, and the operating spring 2043 in the first energy storage mechanism remains in the energy storage state; only when the holding mechanism revokes the first blocking force on the closing release part 104, the balance between the first blocking force and the acting force is broken, and the operating spring 2043 in the first energy storage mechanism will immediately release energy, driving the closing and opening output toggle arm 201 to rotate along the closing direction, so that the first sliding pin shaft of the closing and opening output toggle arm 201 slides from the first opening position a1 in the first chute 6021 to the first closing position a2, realizing closing.
[0114] Specifically, as Figure 7 shown, the closing release part 104 is the first eccentric part 1041 of a first eccentric component rotatably arranged on the frame 60; in the first locked state, the first eccentric part 1041 is lapped by the closing and opening output toggle arm 201; in the first unlocked state, the first eccentric part 1041 disengages from the closing and opening output toggle arm 201; the first eccentric component tends to maintain the first locked state under the action of a reset biasing force.
[0115] For example, as Figure 7 shown, the first eccentric component is an L-shaped or V-shaped bent toggle arm. The bent part of the bent toggle arm is rotatably arranged on the bottom plate 602 of the frame 60. The first force arm end of the bent toggle arm is used as the first eccentric part 1041, and its second force arm end is used as the first limiting part 1042; the length of the first force arm is less than the length of the second force arm, making the first eccentric component a labor-saving lever, so that the holding mechanism applies a smaller blocking force to the first limiting part 1042, and the first eccentric component can be switched between the first locked state and the first unlocked state, that is, the release force required for the closing release part 104 is smaller.
[0116] One end of the reset tension spring 105 is fixed on the support shaft fixed on the frame 60, and the other end is arranged on the first limiting portion 1042 of the bent crank arm. The reset tension spring 105 applies the above-mentioned reset biasing force to the first eccentric portion 1041.
[0117] As Figure 7 shown, the holding mechanism includes a holding member 101 movably arranged on the frame 60 between a state to be lapped and a non-lapped state; in the state to be lapped, the holding member 101 is held by a holding force to lap on the first limiting portion 1042 on the first eccentric member, so as to apply a blocking force to the first eccentric member in the first locked state; the holding force is withdrawn in the non-lapped state.
[0118] For example, as Figure 7 shown, the holding member 101 is the second eccentric portion 1011 of the second eccentric member rotatably arranged on the frame 60. The second eccentric member tends to maintain the state to be lapped under the action of a reset torsion force as the holding force; in the non-lapped state, the second eccentric portion 1011 disengages from the first limiting portion 1042. For example, a first reset torsion spring 103 is sleeved on the second eccentric member. Two ends of the first reset torsion spring 103 are respectively pressed on the closing release plate 1021 (mentioned below) and the support column fixed on the frame 60. The first reset torsion spring 103 applies the reset torsion force to the holding member 101, so that the second eccentric member tends to maintain the state to be lapped.
[0119] Preferably, the second eccentric member is an eccentric half shaft. A first notch 1012 is provided on the outer circumferential wall of the eccentric half shaft. A portion of the second eccentric member opposite to the first notch 1012 forms the second eccentric portion 1011. In Figure 7 shown, under the reset torsion force of the first reset torsion spring 103, the second eccentric portion 1011 tends to face upward.
[0120] As Figure 7 shown, the holding mechanism further includes a first driving mechanism 102 for driving the second eccentric member to rotate to force the second eccentric portion 1011 to withdraw the holding force. The first driving mechanism 102 has two implementation manners. The first driving mechanism 102 is a manual or electric manner.
[0121] As Figure 7As shown, the first driving mechanism 102 is a manual type, which includes a closing release plate 1021, a first driving member 1022 and a first elastic member 1023. Among them, the closing release plate 1021 is fixed on the second eccentric member and avoids the first notch 1012 and the first return torsion spring 103. A first relief hole 10211 serving as a first mating portion is provided on the closing release plate 1021. The first driving member has a first inclined surface that remains in contact with the first mating portion and gradually protrudes toward the first mating portion during telescopic movement to drive the eccentric member to rotate, so as to drive the closing release plate 1021 to drive the closing release fastener 104 to rotate, realizing the switching of the second eccentric member from the to-be-lapped state to the non-lapped state, separating the second eccentric portion 1011 from the first limiting portion 1042, and switching the closing release fastener 104 from the first locked state to the first unlocked state.
[0122] Preferably, as Figure 7 shown, the first driving member 1022 is a closing push rod, and a closing button and a tapered plate are respectively fixed at both ends thereof. The tapered plate is inclined vertically. A first elastic member 1023 is sleeved on the first driving member 1022. The first elastic member 1023 is a spring or a conical spring. Both ends of the first elastic member 1023 are respectively abutted against the closing button and the front plate 601. The closing button and the first elastic member 1023 are both located outside the front plate 601. When it is necessary to drive the holding member 101 to rotate, the closing button is pressed inward, and the first elastic member 1023 is compressed and stores energy. The tapered plate of the first driving member 1022 extends into the first relief hole 10211 serving as the first mating portion, so as to drive the closing release plate 1021 to drive the holding member 101 to rotate counterclockwise in Figure 7 synchronization to realize the unlocked state; after unlocking, the closing button is released, and under the reset of the first elastic member 1023, the first driving member 1022 and the closing button are reset to the starting position. Of course, the closing button and the first elastic member 1023 may not be provided.
[0123] Alternatively, the first driving mechanism 102 is an electric type. As Figure 5 shown, it is a first closing and opening electromagnet 1024. A fixing plate 1025 is fixed on the bottom plate 602. A second mating portion for cooperating with the telescopic shaft of the first closing and opening electromagnet 1024 is further provided on the closing release plate 1021. For example, the second mating portion is a mating hole. In a manner similar to the first inclined surface above, the mating hole and the telescopic shaft are also cooperated through a downwardly inclined second inclined surface. After the first closing and opening electromagnet 1024 is powered on, the telescopic shaft of the first closing and opening electromagnet 1024 makes an extending movement, applies a force to the closing release plate 1021 to drive the closing release plate 1021 to rotate, and finally drives the second eccentric member to rotate counterclockwise to realize the cancellation of the holding force of the second eccentric portion 1011 on the first limiting portion 1042.
[0124] That is, with the cooperation of the first driving mechanism 102 and the first reset torsion spring 103, the second eccentric part 1011 of the second eccentric member can be switched between the to-be-lapped state and the non-lapped state, and further, the closing release 104 can be switched between the first unlocked state and the first locked state.
[0125] Furthermore, optimally, the first eccentric part 1041 is rollingly abutted against the outer peripheral wall surface of the end of the first crank arm end 2011; the second eccentric part 1011 is located on the rotation circumference of the first limiting part 1042; in the first unlocked state, when the closing and opening output crank arm 201 rotates in the opening direction, a first abutting force in the same direction as the reset biasing force is applied to the first eccentric member by rolling friction of the first eccentric part 1041. Under the combined action of the first abutting force and the reset biasing force of the reset tension spring 105, the first eccentric part 1041 is forced to switch from the first unlocked state to the first locked state; and the first limiting part 1042 applies a second abutting force opposite to the reset torsion to the second eccentric part 1011, forcing the second eccentric part 1011 to switch from the initial to-be-lapped state, cross the non-lapped state, and then switch back to the to-be-lapped state.
[0126] At this time, as Figure 6b and Figure 6c shown, when the closing and opening output crank arm 201 rotates in the opening direction, the first crank arm end 2011 rolls on the first eccentric part 1041 to apply a first abutting force to the first eccentric part 1041. Under the combined action of the first abutting force and the reset biasing force, the first limiting part 1042 rotates clockwise. The first limiting part 1042 gradually transitions from the flat surface that does not abut the first notch to the flat surface that abuts the first notch 1012, and applies a second abutting force to this flat surface. Under the action of the second abutting force and the reset tension spring 105, overcoming the reset torsion of the first reset torsion spring, the second eccentric member is driven to rotate counterclockwise in Figure 6b so that the second eccentric part 1011 is switched from the to-be-lapped state to the non-lapped state; when the first limiting part 1042 rotates out from the top of the first notch 1012, the second abutting force on the second eccentric member is released, and the second eccentric member rotates clockwise under the reset torsion of the first reset torsion spring 103 and returns to the to-be-lapped state, so that the first limiting part is again lapped on the second eccentric part. That is, the first abutting force applied by the closing and opening output crank arm 201 to the first eccentric part 1041 during the opening process further promotes the first eccentric member to switch from the first unlocked state to the first locked state, preparing for the next closing of the closing and opening output crank arm 201.
[0127] Optimally, as Figure 7As shown, a rolling element is rotatably provided on the first eccentric part 1041. The first eccentric part 1041 is in rolling contact with the first crank arm end 2011 through the rolling element, reducing the rolling friction therebetween. Since in a force-saving lever, the length of the first force arm is less than that of the second force arm, through the arrangement of the rolling element, the rolling friction between the first eccentric part 1041 corresponding to the first force arm and the first crank arm end 2011 is further reduced, reducing the friction between the first limiting part 1042 corresponding to the second force arm and the second eccentric part 1011. Further, during the closing and tripping process, the tripping force required for the first driving mechanism 102 to drive the second eccentric component to rotate is further reduced. Optionally, the rolling element is a bearing or a roller.
[0128] IV. Tripping Module
[0129] As Figure 8a , Figure 8b , Figure 9 , Figure 10a , Figure 11a As shown, the tripping module is a tripping release device 30, which includes a tripping release 301 and a second energy storage mechanism. The tripping release 301 is movably provided on the frame 60 between a second locked state and a second unlocked state; the second energy storage mechanism has a tripping fastener 303 rotatably provided on the closing and opening main shaft 202. The tripping fastener 303 is driven in linkage by a fifth driving force of the main shaft crank arm 203 rotating in the closing direction, so that the second energy storage mechanism stores energy; the tripping fastener 303 is driven in linkage to drive the main shaft crank arm 203 to rotate in the tripping direction due to the release of energy by the second energy storage mechanism; in the second locked state, the tripping release 301 is subject to a fourth blocking force that balances the fifth driving force acting on the linkage crank arm 3032 of the tripping fastener 303 by the main shaft crank arm 203. In the second unlocked state, the balance of the fourth blocking force is cancelled. The two states of the tripping release 301 enable the closing and opening output crank arm 201 to perform a tripping release first during the tripping action, and then perform the tripping action.
[0130] Specifically, as Figure 8a , Figure 8b , Figure 9 and Figure 11a shown, the second energy storage mechanism further includes a tripping spring 305. One end of the tripping spring 305 is fixed on a support shaft fixed on the front plate 601, and the other end is hooked on the tripping fastener 303;
[0131] As Figure 9As shown in the figure, the opening fastener 303 includes a body, two limit crank arms 3031, a linkage crank arm 3032 and a fixing column 3033. Among them, the body is sleeved on the opening and closing main shaft 202; the two limit crank arms 3031 are respectively fixed at both axial ends of the body, the fixing column is fixedly connected between two adjacent limit crank arms 3031, and one end of the release spring 305 is fixed on the fixing column. As Figure 10a shown in the figure, a driving pin 2032 is provided on the main shaft crank arm 203, and the driving pin 2032 passes through the relief hole on the middle partition plate 603 and is in a linkage abutting setting with the linkage crank arm 3032 of the opening fastener 303.
[0132] As Figure 8a shown in the figure, the structure of the opening release fastener 301 is similar to that of the above-mentioned closing release fastener 104. The opening release fastener 301 is the third eccentric part of the third eccentric component rotatably provided on the front plate 601 of the frame 60. Optionally, the structure of the third eccentric component is the same as that of the above-mentioned second eccentric component. The third eccentric part switches between the to-be-lapped state and the non-lapped state and tends to remain in the to-be-lapped state under the reset torque.
[0133] Similarly, as Figure 8a shown in the figure, the third eccentric component is an eccentric half shaft. A second notch 3011 is provided on the eccentric half shaft, and the part opposite to the second notch 3011 is the third eccentric part. A second reset torsion spring 306 is sleeved on the second eccentric component. The second reset torsion spring 306 applies a reset torque to the third eccentric component. In the second locked state, the end of the limit crank arm 3031 of the opening fastener 303 is lapped on the third eccentric part. In the second unlocked state, the end of the limit crank arm 3031 of the opening fastener 303 is separated from the third eccentric part.
[0134] The limit crank arm 3031 is subjected to the blocking force from the third eccentric part, which balances the pulling force of the linkage crank arm 3032 by the main shaft crank arm 203 in the closing direction, so that the opening fastener 303 is kept in the first locked state. When the blocking force on the third eccentric part is withdrawn, the balance between the blocking force and the pulling force is broken. After the release spring 305 releases energy, it drives the opening fastener 303 to rotate in the opening direction, and reversely drives the main shaft crank arm 203 to rotate in the opening direction. Furthermore, the first energy storage mechanism stores energy during the opening process and immediately releases energy, driving the opening and closing output crank arm 201 to rotate in the opening direction to realize the opening action.
[0135] Similarly, similar to the above-mentioned first driving mechanism 102, a second driving mechanism 304 is provided in the opening release device 30. The second driving mechanism 304 has an electric form and a manual form. Among them, as Figure 8aAs shown, the second driving mechanism 304 in manual form includes a second driving member 3042, a closing release latch 302, a second elastic member 3043, a closing button 3041, and a guide sleeve 3044. The two ends of the second driving member 3042 serve as an operating end and a connecting end respectively; for example, the second driving member 3042 is a closing push rod, and the connecting end abuts against the closing release latch 302 through a downwardly inclined second inclined surface. For example, a first transition member 3045 is sleeved outside the connecting section, and the outer peripheral surface of the first transition member 3045 is a conical surface, and the conical surface serves as the second inclined surface. In Figure 8a the diameter of the conical surface gradually decreases in the direction from the outside of the front plate 601 towards the inside of the front plate 601.
[0136] For example, the closing release latch 302 is fixed on the third eccentric member, and a roller is rotatably installed on the inner end of the closing release latch 302. The conical surface of the first transition member 3045 abuts against the roller, and the axial direction of the roller intersects with the telescopic movement direction of the second driving member 30423042. A rolling friction is formed between the conical surface and the outer peripheral surface of the roller, which is convenient for the conical surface to drive the roller to rotate, so as to drive the closing release latch 302 to rotate and then drive the closing release member 301 to rotate, so as to cancel the blocking force of the closing release member 301 on the closing latch 303.
[0137] Similar to the first driving mechanism 102, the closing button 3041 is fixed on the operating end of the second driving member 3042. The second elastic member 3043 is sleeved on the second driving member 3042, and the two ends of the second elastic member 3043 abut against the outside of the front plate 601 and the inside of the closing button 3041 respectively. For example, the second elastic member 3043 is a compression spring or a conical spring; the guide sleeve 3044 has a guide channel along the telescopic direction of the second driving member 3042, is sleeved on the second driving member 3042 and fixed on the outer side wall of the front plate 601, and is located between the outside of the front plate 601 and the closing button 3041. By directly pressing the closing button 3041 inward, the closing release member 301 can be driven to Figure 8b rotate counterclockwise in the, so that the third eccentric part is separated from the limit crank arm 3031 and is in the first unlocking state.
[0138] Similarly, as Figure 8b shown, the second driving mechanism 304 is an electric driving mode. At this time, the second driving mechanism 304 is a second closing and opening electromagnet 3046. Correspondingly, a mating hole for mating with the telescopic shaft of the second closing and opening electromagnet 3046 is provided on the closing release latch 302. After the second closing and opening electromagnet 3046 is energized, the telescopic shaft makes an extending movement to drive the closing release latch 302 and the closing release member 301 to rotate counterclockwise, so that the third eccentric part is separated from the limit crank arm 3031 and is in the first unlocking state.
[0139] The second drive mechanism 304 is provided to meet the requirement that under other working conditions or when the operator knows that opening the circuit breaker is required, the second drive mechanism 304 can be manually operated without the need for the ejector mechanism to cause the opening circuit breaker tripping device 30 to perform a tripping action, thereby increasing the scope of use of the operating system and providing a variety of drive modes for the tripping action.
[0140] Based on the above-mentioned energy storage module 20, closing module and opening module, the energy storage process, closing process and opening process of the operating system are described below respectively.
[0141] The energy storage module 20 has two energy storage processes, namely, energy storage by the first energy storage mechanism and energy storage by the second energy storage mechanism during the closing process:
[0142] like Figure 3 As shown, when manually charging, Figure 3 In the state shown, the separation and combination main shaft 202 is rotated clockwise, and the separation and combination main shaft 202 drives the main shaft crank arm 203 to rotate. The first end 20421 of the first spring pin 2042 is acted upon by the end wall of the third end 20311 of the third sliding groove on the main shaft crank arm 203, and is pushed by the main shaft crank arm 203, driving the first spring crank arm 2041 to rotate clockwise together, thereby causing the operating spring 2043 to be compressed during the rotation of the first spring crank arm 2041. During this process, the second end 20421 of the first spring pin 2042 is pressed against the main shaft crank arm 203, and the first spring crank arm 2041 is pressed against the main shaft crank arm 203. 22 slides in the fourth slide groove 2014 on the separation and combination output crank arm 201 until the operating spring is compressed past the dead point, and the second end 20422 of the first spring pin 2042 abuts against the third crank arm end 2013 of the separation and combination output crank arm 201. At this time, the first crank arm end 2011 of the separation and combination output crank arm 201 is supported by the bearing on the first eccentric part 1041 of the first eccentric part, and the first eccentric part 1041 applies a first blocking force to the first crank arm end 2011, so that the operating spring 2043 remains in the energy storage state. While the operating spring 2043 stores energy, the driving pin 2032 on the main shaft crank arm 203 drives the opening brake fastener 303 to rotate, and the limit crank arm 3031 on the opening brake fastener 303 rotates clockwise, and the end of the limit crank arm 3031 gradually embeds into the second notch 3011, overcoming the reset torque of the second reset torsion spring 306 and abutting against the flat surface of the second notch 3011, driving the third eccentric component to rotate counterclockwise, and the third eccentric part switches from the waiting overlap state to the non-overlap state. After the end of the crank arm 3031 rotates out from the top of the second incision 3011, the third eccentric part rotates clockwise under the reset torque of the second reset torsion spring 306, so that the second eccentric part 1011 switches from a non-overlapping state to an overlapping state, and then the limiting crank arm 3031 overlaps the third eccentric part; this process causes the release spring to be stretched to store energy. Before the operating spring 2043 reaches the energy storage position, the limiting crank arm 3031 first overlaps the third eccentric part, and the release tension spring 305 completes the energy storage first.
[0143] The closing process is as follows:
[0144] When manually closing, press the closing button inward to drive the closing push rod to retract. Use the inclined plane on the tapered plate of the push rod to push the closing release plate 1021 and the second eccentric member to rotate. As shown in Figure 3 the counterclockwise rotation in the figure, and then the second eccentric part 1011 of the second eccentric member separates from the first limiting part 1042 of the first eccentric member that it abuts against during the rotation process. At this time, the force balance maintained by the first limiting part 1042 and the first eccentric part 1041 of the first eccentric member due to abutting against the second eccentric part 1011 and the first crank end 2011 of the closing and opening output crank 201 is broken, that is, the bearing of the first eccentric part 1041 on the first eccentric member no longer limits the closing and opening output crank 201;
[0145] At this time, the operating spring 2043 instantaneously releases energy. Under the action of the operating spring 2043, the first end 20421 of the first spring pin 2042 on the first spring crank 2041 slides from the third end 20311 to the fourth end 20312 in the third chute 2031 on the main shaft crank 203 and will not interfere with the drive pin 2032 on the main shaft crank 203. During this process, the second end 20422 of the first spring pin 2042 abuts against the third crank end 2013 and gives a thrust to the closing and opening output crank 201 to push the closing and opening output crank 201 to rotate Figure 3 clockwise in the figure until the first sliding pin shaft 2015 on the closing and opening output crank 201 reaches the first closing position a2 of the first chute 6021 on the bottom plate 602, and the closing is completed.
[0146] The rotation of the second eccentric member for electric closing is similar to that of manual closing, except that the closing push rod in the first driving mechanism 102 is replaced by the first closing and opening electromagnet 1024. After the first closing and opening electromagnet 1024 is energized, the telescopic shaft on the first closing and opening electromagnet 1024 makes an extending movement and abuts against the closing release plate 1021 through an inclined plane, thereby driving the closing release plate 1021 and the closing release part 104 to rotate and realizing the above-mentioned closing process.
[0147] In addition, during the rotation of the closing and opening output crank 201 in the closing direction, the first crank end 2011 of the closing and opening output crank 201 will apply a abutting force to the first eccentric part 1041. As shown in Figure 6a the figure, the first eccentric part rotates counterclockwise, and the first limiting part 1042 is located in the first notch but does not abut against the flat surface of the first notch to separate from the first notch 1012.
[0148] The opening process is as follows:
[0149] As shown in Figure 8bAs shown, when the gate is manually opened, after pressing the gate opening button 3041, the gate opening push rod moves inward, and the inclined surface on the gate opening push rod acts on the roller. Under the pushing action of the inclined surface on the gate opening push rod, the gate opening release plate 302 overcomes the reset torque of the second reset torsion spring 306 and rotates counterclockwise, thereby driving the third eccentric component to rotate counterclockwise, and the third eccentric part switches from the overlapping state to the non-overlapping state until the limiting crank arm 3031 of the gate opening fastener 303 is separated from the third eccentric part. The opening latch 303 rotates counterclockwise under the tension generated by the release of energy of the tripping tension spring 305, and at the same time, the linkage crank arm 3032 of the opening latch 303 reversely drives the driving pin 2032 to rotate counterclockwise, so as to drive the main shaft crank arm 203 connected with the driving pin 2032 to rotate counterclockwise. During the counterclockwise rotation of the main shaft crank arm 203, the first end 20421 of the first spring pin 2042 on the first spring crank arm 2041 abuts against the fourth end 20312 of the third sliding groove 2031. On the end wall, the end wall of the fourth end 20312 of the third slide groove 2031 pushes the first spring pin 2042 to drive the first spring arm 2041 to rotate counterclockwise, so that the operating spring 2043 is compressed and passes the dead point, and the energy of the release tension spring 305 is released. During this process, the second end 20422 of the first spring pin 2042 slides from the third arm end 2013 of the fourth slide groove 2014 on the separation and combination output arm 201 to the second arm end 2012 (counterclockwise rotation). Thereafter, under the further drive of the operating spring 2043 releasing energy, the second end 20422 of the first spring pin 2042 applies a pushing force to the second crank arm end 2012 of the fourth slide slot 2014, driving the splitting and combining output crank arm 201 to rotate counterclockwise until the first sliding pin shaft 2015 on the splitting and combining output crank arm 201 passes through the first slide slot 6021 on the bottom plate 602 and reaches the first opening position a1, completing the opening action.
[0150] The rotation of the third eccentric component can achieve electric closing and manual closing. The two are similar, with the difference that the opening push rod in the second driving mechanism 304 is replaced by the second opening and closing electromagnet 3046. After the second opening and closing electromagnet 3046 is energized, the telescopic shaft on the second opening and closing electromagnet 3046 extends out and abuts against the hole on the opening release plate 302 through the inclined surface, thereby driving the opening release plate 302 and the opening release member 301 to rotate, thereby realizing the above-mentioned opening process.
[0151] In addition, during the opening process of the opening and closing output crank arm 201, driven by the operating spring 2043, the opening and closing output crank arm 201 rotates in the opening direction, such as from Figure 6bRotating counterclockwise, the first arm end 2011 on the opening and closing output link 201 applies a first abutting force to the first eccentric part 1041 through the bearing on the first eccentric part 1041 by rolling friction. Under the combined action of the first abutting force and the restoring biasing force of the restoring spring 105, the first eccentric component is driven to rotate clockwise as a whole, and then the first limiting part 1042 is driven to gradually abut against the flat surface of the first notch, applying a second abutting force to the flat surface of the first notch 1012 to overcome the restoring torque of the first restoring torsion spring 103, so as to drive the second eccentric component to rotate counterclockwise. The second eccentric part 1011 is switched from the waiting-to-lap state to the non-lapped state. When the first limiting part 1042 rotates out from the top of the first notch 1012, the second eccentric component rotates clockwise under the restoring torque of the first restoring torsion spring 103, and the second eccentric part 1011 is switched from the non-lapped state to the waiting-to-lap state again, so that the first limiting part 1042 is lapped on the second eccentric part 1011 again, and the first eccentric part 1041 abuts against the first arm end 2011 of the opening and closing output link 201, and its state is as Figure 6a shown, and then the first eccentric component is switched from the first unlocking state to the first locking state, facilitating the next closing operation.
[0152] V. Grounding Module
[0153] As Figure 10a , Figure 10b and Figure 11a shown, the grounding module is the grounding opening and closing device 40, which includes a grounding main shaft 402, a grounding output link 401 and the above-mentioned first energy storage mechanism.
[0154] The grounding main shaft 402 is rotatably arranged on the front plate 601, the middle partition plate 603 and the bottom plate 602, and the grounding output link 401 is sleeved on the grounding main shaft 402.
[0155] The first energy storage mechanism also has a second spring link 405 fixedly arranged on the grounding main shaft 402, and one end of the second spring link 405 is linked with the grounding output link 401; both ends of the operating spring 2043 are respectively arranged on the first spring link 2041 and the second spring link 405. The second spring link 405 is driven by the grounding main shaft 402 to rotate, so that the operating spring 2043 stores energy; the grounding output link 401 is driven by the second spring link 405 due to the release of energy of the operating spring 2043, and can be rotatably switched between the second opening position b1 and the second closing position b2 on the frame 60.
[0156] The first energy storage mechanism 204 also includes a second spring head and a second spring pin fixed on the free end of the second spring link. A fifth chute 4011 is arranged on the grounding output link. One end of the second spring pin 403 is slidably arranged in the fifth chute 4011. As Figure 11aAs shown, the second spring crank arm 405 is fixedly sleeved on the grounding main shaft 402. The second spring crank arm 405 has a sleeved portion sleeved on the grounding main shaft 402 and a free end provided on the sleeved portion and extending radially outward. The second spring pin is fixed on the free end, and one end of the second spring pin 403 is slidably arranged in the fifth chute 4011 of the grounding output crank arm 401; the second spring head is fixed on the second spring pin, and both ends of the operating spring abut against the first spring head and the second spring head respectively.
[0157] When the operating spring 2043 is in the energy storage state, the second spring pin 403 can slide in the fifth chute 4011 under the drive of the grounding main shaft and the second spring crank arm; when the operating spring 2043 releases the stored energy, the second spring pin 403 is driven by the operating spring 2043 to apply a fourth pushing force to the end wall at one end of the fifth chute 4011 to drive the grounding output crank arm 401 to rotate.
[0158] When grounding and closing, as Figure 10b and Figure 11a shown, rotate the grounding main shaft 402 clockwise from the state in Figure 11a . The second spring crank arm 405 rotates with the grounding main shaft 402. One end of the second spring pin 403 rotates from the sixth end 4013 of the fifth chute 4011 towards the fifth end 4012 until it reaches the fifth end. During this process, the operating spring 2043 is compressed. When the operating spring 2043 passes the dead point, the energy of the operating spring 2043 is released. One end of the second spring pin 403 collides with and pushes the grounding output crank arm 401 to rotate clockwise until the second sliding pin shaft 4014 of the grounding output crank arm 401 slides from the second opening position of the second chute on the bottom plate to the second closing position b2 of the second chute 6022 on the bottom plate 602, and the grounding closing action ends, as shown in the state in Figure 11b .
[0159] On the contrary, when grounding and opening, as Figure 11b shown, rotate the grounding main shaft 402 counterclockwise from the state in Figure 11b . One end of the second spring pin 403 slides in the fifth chute 4011 from the fifth end 4012 to the sixth end 4013. During this process, the operating spring 2043 is compressed. When the operating spring 2043 passes the dead point, the energy of the operating spring 2043 is released. One end of the second spring pin 403 collides with and pushes the grounding output crank arm 401 to rotate counterclockwise until the second sliding pin shaft 4014 of the grounding output crank arm 401 slides from the second closing position in the second chute on the bottom plate to the limited second opening position b1 of the second chute 6022 on the bottom plate 602, and the grounding opening action ends, as shown in the states in Figure 8a and Figure 8b .
[0160] VI. Indicator module
[0161] As Figure 12 , Figure 13 , Figure 14a , Figure 14b shown, the operating system further includes an indicating device 50, and the indicating device 50 includes a linkage member 501 rotatably provided on a frame 60 between a first state and a second state;
[0162] In the first state, the linkage member 501 is driven to rotate by the linkage of the closing and opening output crank arm 201, and when the closing and opening output crank arm 201 is in the first closing position a2, a second blocking force is applied to the grounding output crank arm 401 to force the grounding output crank arm 401 to remain in the second opening position b1, and the second blocking force is released when the closing and opening output crank arm 201 is in the first opening position a1;
[0163] In the second state, the linkage member 501 is driven to rotate by the linkage of the grounding output crank arm 401. When the grounding output crank arm 401 is in the second closing position b2, a third blocking force is applied to the closing and opening output crank arm 201 to force the closing and opening output crank arm 201 to remain in the first opening position a1, and the third blocking force is released when the grounding output crank arm 401 is in the second opening position b1;
[0164] An indicating member 503, fixedly connected to one end of the linkage member 501, for indicating the opening position or closing position of the grounding crank arm and the closing and opening output crank arm.
[0165] For this indicating device 50, the linkage member 501 is directly linked with the closing and opening output crank arm 201 and the grounding output crank arm 401. When the closing and opening output crank arm 201 is in the closing state, the linkage member 501 applies a second blocking force to the grounding crank arm to limit the grounding crank arm from performing a closing action and keep it in the opening state; when the grounding output crank arm 401 is in the closing state, the linkage member 501 applies a third blocking force to the closing and opening output crank arm 201 to limit the closing and opening output crank arm from performing a closing action and keep it in the opening state, thereby ensuring that when performing a grounding closing, the closing and opening output crank arm must be in the opening position, otherwise the grounding closing action cannot be performed; on the contrary, when performing the closing of the closing and opening output crank arm, the grounding output crank arm must be in the opening position, otherwise the closing action of the closing and opening output crank arm cannot be performed, thus forming a safety protection component to ensure that the operator is in a safe state at all times when performing the closing and opening operations and improving the safety performance of the operating system.
[0166] In the first state, the indicating member 503 and the linkage member 501 move synchronously with the opening / closing output toggle arm 201, so that the indicating member 503 can accurately indicate whether the opening / closing output toggle arm 201 is in the opening position or the closing position; in the second state, the indicating member 503 and the linkage member 501 move synchronously with the grounding output toggle arm, so that the indicating member 503 can accurately indicate whether the grounding output toggle arm is in the opening position or the closing position. Then, through the setting of the linkage member 501, only one indicating member needs to be set to accurately indicate the positions of the opening / closing output toggle arm 201 and the grounding output toggle arm 401, making the indicating device 50 more compact in structure while ensuring accurate indication, occupying less space, and further making the structure of the entire operating system compact and occupying less space.
[0167] Optionally, the indicating member is an indicating disk, and the indicating disk is a partial arc. Marks indicating the opening direction and the closing direction can be provided on the indicating disk, or marks indicating the opening direction and the closing direction can be provided on the frame. Generally, the closing direction and the opening direction of the grounding output toggle arm and the opening / closing output toggle arm are the same. For example Figure 10a in, the closing directions of both the grounding output toggle arm and the opening / closing output toggle arm are counterclockwise, and the opening directions are both clockwise.
[0168] Specifically, as Figure 14b shown, the linkage member 501 includes a circular body and a third eccentric portion that protrudes radially and extends circumferentially on the circular body; a radially extending notch groove 5012 is provided on the circular body, and a first arc-shaped hole 5011 is provided on the linkage member 501; the first arc-shaped hole 5011 includes a first arc-shaped hole segment 20111 provided on the circular body and concentric with the rotation axis of the circular body, and a second arc-shaped hole segment 20112 provided on the third eccentric portion and eccentric with the rotation axis of the circular body; the first arc-shaped hole segment 20111 intersects with the first sliding groove 6021 in the axial direction of the opening / closing main shaft 202.
[0169] In the first state, the first sliding pin shaft 2015 slides in the second arc-shaped hole segment 20112 and applies a driving force to the second arc-shaped hole segment 20112 to drive the linkage member 501 to rotate; the second sliding pin shaft 4014 is tangent to the outer peripheral wall of the circular body and is subjected to a second blocking force applied by the outer peripheral wall to keep the grounding output toggle arm 401 in the second closing position b2; in the second state, the first arc-shaped hole segment 20111 slides on the second sliding pin shaft 4014 and applies a third blocking force to the second sliding pin shaft 4014; the second sliding pin shaft 4014 slides reciprocally in the notch groove 5012 and applies a thrust to the notch groove 5012 to drive the linkage member 501 to rotate.
[0170] The first arc-shaped hole 5011 further includes a third arc-shaped hole, which transitionally connects the proximities of the second arc-shaped hole 20112 and the first arc-shaped hole 20111; the rotation axis of the third arc-shaped hole is eccentric to the rotation axes of both the first arc-shaped hole 20111 and the second arc-shaped hole 20112; in the second state, the first sliding pin shaft 2015 is located in the third arc-shaped hole. That is to say, the above-mentioned second arc-shaped hole 20112 is a special-shaped arc hole that facilitates the smooth sliding of the first sliding pin shaft 2015 on the output toggle arm 201 in the first chute 6021 and this second section. That is to say, the two ends of the first arc-shaped hole are respectively the closing corresponding position e, the blocking position c, and the opening corresponding position d, where the section between the blocking position c and the opening corresponding position d serves as the first arc-shaped hole 20111, the section between the opening corresponding position d and the closing corresponding position e serves as the second arc-shaped hole 20112, and the transition section where the opening corresponding position d is located serves as the third arc-shaped hole.
[0171] Due to the three-position operating system, under normal operation, the opening and closing output toggle arm 201 is in the closing state, and the grounding output toggle arm 401 is in the opening state. When an operator needs to perform maintenance or other operations on the circuit, the opening and closing output toggle arm 201 needs to be first actuated to open, and then remain in the open state; then the grounding output toggle arm is operated to close, connecting the ground to the circuit, and only then can the operator perform maintenance work or other operations. After the operations are completed, the grounding opening operation is first performed. When the grounding output toggle arm is in the open state, the opening and closing output toggle arm is then actuated to close. That is, the opening and closing main shaft 202 and the grounding main shaft 402 cannot rotate simultaneously. Usually, a locking plate 80 is sleeved on the opening and closing main shaft 202 and the grounding main shaft 402. The two ends of the locking plate 80 are respectively fitted with the opening and closing main shaft 202 and the grounding main shaft 402 through non-circular holes, and the opening and closing main shaft 202 and the grounding main shaft 402 cannot rotate simultaneously, as Figure 10b shown. Or, instead of setting this locking plate 80, the above-mentioned linkage component 501 can also be used to achieve that the opening and closing main shaft 202 and the grounding main shaft 402 cannot perform opening and closing operations simultaneously.
[0172] Specifically, as Figures 15a to 15c schematically shows the linkage component in the first state. In Figure 15aIn it, the second sliding pin shaft 4014 of the grounding output toggle arm 401 is in the second opening position b1, that is, the grounding output toggle arm 401 is in the opening state, and the first sliding pin shaft 2015 of the opening and closing output toggle arm is in the second closing position b2, that is, the opening and closing output toggle arm 201 is in the closing state; in this state, since the second sliding pin shaft 4014 on the grounding output toggle arm 401 is tangent to the outer peripheral wall of the circular body, the outer wall surface of the circular body exerts a second blocking force on the second sliding pin shaft, and the second sliding pin shaft is blocked by the outer peripheral wall of the circular body of the linkage member 501 and cannot slide along the second chute 6022 to perform the closing action. Therefore, the second sliding pin shaft of the grounding output toggle arm 401 cannot be changed to the second closing position b2. When the opening and closing output toggle arm 201 starts the opening process, the first sliding pin shaft 2015 on the opening and closing output toggle arm slides from the first closing position a2 to the first opening position a1 in the first chute 6021 and slides in the second arc-shaped hole 20112 on the linkage member 501 to drive the linkage member 501 to rotate clockwise through Figure 15b state until Figure 15c state. At this time, the first sliding pin shaft slides to the first opening position a1, that is, the opening and closing output toggle arm 201 is in the opening state. At this time, the second sliding pin shaft of the grounding output toggle arm still remains in the second opening position. In this state, the opening and closing output toggle arm 201 can perform the next opening and closing operation.
[0173] When both the opening and closing output toggle arm 201 and the grounding toggle arm are in the opening state, due to the cancellation of the second blocking force, the grounding output toggle arm can perform the closing action. As Figure 15c shown, the second sliding pin shaft 4014 is just located at the notch of the notch groove 5012. When the grounding output toggle arm 401 is rotated counterclockwise, the second sliding pin shaft 4014 on the grounding output toggle arm 401 slides along the second chute 6022 and also slides along the notch groove 5012, thus pushing the linkage member 501 to rotate further clockwise. When the second sliding pin shaft 4014 of the grounding output toggle arm 401 passes through Figure 15d state (that is, the second sliding pin shaft first slides from the notch to the bottom of the groove, and the linkage member continues to rotate clockwise), Figure 15e state (that is, the second sliding pin shaft slides from the bottom of the groove towards the notch, and the linkage member continues to rotate clockwise) to reach Figure 15f the second closing position b2 shown, that is, the grounding output toggle arm completes the closing action. During this process, the first sliding pin shaft of the opening and closing output toggle arm still remains in the first opening position a1, that is, the opening and closing output toggle arm still remains in the opening state. At this time, the first chute 6021 basically intersects with the first arc-shaped hole 20111, thus restricting the opening and closing operation of the opening and closing output toggle arm. Therefore, the setting of the linkage member 501 cannot perform the grounding output operation when the opening and closing output toggle arm 201 is in the closing state, and cannot perform the opening and closing operation when the grounding output toggle arm 401 is in the closing state.
[0174] Therefore, the setting of the linkage component, on the one hand, when the opening / closing output rocker arm is in the closing state, the earthing opening / closing operation cannot be performed, and when the earthing output rocker arm is in the closing state, the opening / closing operation of the opening / closing output rocker arm cannot be performed. Thus, it is ensured that when the operator operates the earthing main shaft for earthing opening / closing or operates the opening / closing main shaft for the opening / closing operation of the opening / closing output rocker arm, electric shock will not occur, improving the safety of the operating system and facilitating the operator to operate the system. On the other hand, due to the limiting effect of the linkage component, only one indicating disk and a transmission mechanism need to be set, and the positions of the opening / closing output rocker arm and the earthing output rocker arm can be accurately indicated. While the indicating device is accurate in indication, its structure is more compact, occupying less space, and further making the structure of the entire operating system compact and occupying less space.
[0175] The transmission mechanism and the linkage component are distributed on both sides of the bottom plate. A connecting rotating shaft is provided on the bottom plate. The first end of the transmission mechanism and the linkage component are respectively fixed at both ends of the connecting rotating shaft. The second end of the transmission mechanism extends and passes through the front plate and projects outwards. The indicating disk is located outside the front plate. During actual use, the front plate faces the operator side, and the indicating marks of the above-mentioned opening direction and closing direction can be set on the front plate.
[0176] As Figure 13 shown, the transmission mechanism is a four-bar linkage mechanism 502, which includes a first link 5021, a second link 5022, a third link 5023, and an indicating output shaft 5024. Among them, both ends of the first link 5021 are respectively hinged to the second link 5022 and the third link 5023; the end of the second link 5022 far from the first link 5021 is fixedly sleeved on the connecting shaft; the end of the third link 5023 far from the first link 5021 is fixedly connected to one end of the indicating output shaft 5024, and the other end of the indicating output shaft 5024 is fixedly connected to the indicating disk. The first link 5021, the second link 5022, and the third link 5023 form the four-bar linkage mechanism 502. When the linkage component 501 rotates, the indicating output shaft 5024 and the indicating disk are driven to rotate synchronously through the four-bar linkage mechanism 502, so as to realize the synchronous rotation of the indicating disk and the opening / closing output rocker arm 201 or the earthing output rocker arm 401. As a deformation, the transmission mechanism can also be other structures. For example, the transmission mechanism includes an indicating output shaft 5024, and both ends of the indicating output shaft 5024 are respectively used as the first end and the second end.
[0177] The first sliding pin shaft mentioned above is fitted into the first arc-shaped hole, and the second sliding pin shaft is fitted into the notch groove. As a variation, the two are swapped, with the first sliding pin shaft fitted into the notch groove and the second sliding pin shaft fitted into the first arc-shaped hole. As a variation, the linkage component can also be of other structures, as long as it can achieve that when the closing-opening toggle arm is in the closing state, a second blocking force is applied to the grounding output toggle arm, and the grounding output toggle arm cannot perform the closing-opening action; when the grounding output toggle arm is in the closing state, a third blocking force is applied to the closing-opening output toggle arm, and the closing-opening output toggle arm cannot perform the closing-opening action.
[0178] As Figure 16 shown, in addition, the frame 60 further includes a mounting seat 604 provided outside the bottom plate 602, and the mounting seat 604 is provided with a relief hole for avoiding the closing-opening output toggle arm 201 and the grounding output toggle arm 401. During use, this operating system is installed on the gas-insulated switchgear. Since the gas-insulated switchgear will deform during the air-filling process of its inner cavity, by setting the mounting seat 604 and fixing the mounting seat 604 on the gas-insulated switchgear, the firmness of installing the operating system on the gas-insulated switchgear is enhanced; at the same time, the setting of the mounting seat 604 facilitates opening mounting holes on the mounting seat 604 arbitrarily according to the shape of the gas-insulated switchgear under different working conditions, which is convenient for installing this operating system on the gas-insulated switchgear under different working conditions and enlarges the application range of this operating system. The setting of the middle partition plate 603 strengthens the firmness and supporting force of the closing-opening main shaft 202 and the grounding main shaft 402 when installed on the front plate 601 and the bottom plate 602.
[0179] As a variation, the above-mentioned first sliding pin shaft is fitted with the notch groove, corresponding to the second sliding pin shaft being fitted with the first arc-shaped hole, and its movement process is similar to the above, so it will not be elaborated.
[0180] VII. Electric Module:
[0181] The rotation of the closing-opening main shaft 202 can be manually driven or electrically driven. Among them, as Figure 4 shown, the electric module mainly includes an electric driving mechanism 70, a microswitch, and an indicating disk fixed on the closing-opening main shaft 202. The electric driving mechanism 70 includes a motor 71, a motor 71 toggle arm, a driving connecting rod 73, and a main shaft toggle arm 203 fixed on the closing-opening main shaft 202. Among them, the motor 71 is installed on the bottom plate 602. One end of the motor 71 toggle arm is connected to the output shaft of the motor 71, and the other end is hinged on the driving connecting rod 73. The other end of the driving connecting rod 73 far from the motor 71 toggle arm is connected to the main shaft toggle arm 203 through a driving shaft, thus forming a crank-rocker mechanism.
[0182] When the motor 71 rotates, the crank rocker mechanism drives the separation and closing main shaft 202 to rotate until the operating spring 2043 reaches the predetermined energy storage position, the arc of the indicator disk on the separation and closing main shaft 202 presses the micro switch, and the motor 71 stops rotating to realize the electric energy storage action. Since this electric module transmits the motion to the separation and closing main shaft 202 through a crank rocker structure, when the motor 71 rotates, after the crank rocker passes the dead point, the main shaft crank arm 203 will rotate, and the rotation angle is equal to the previous rotation angle. In other words, in the end, only the motor 71 needs to rotate in one direction to realize the angle switching of the main shaft crank arm 203 in the separation and closing action, which greatly simplifies the production cost of parts.
[0183] In the operating system of this embodiment, when the operator performs manual closing, the operator first applies a driving force along the closing direction to the separation and closing main shaft to drive the separation and closing main shaft to drive the main shaft crank arm to rotate in the closing direction, and then drives the first spring pin in linkage to allow the first energy storage mechanism to store energy. Since the closing release member in the closing release device is subjected to the first blocking force, the force acting on the first crank arm end of the separation and closing output crank arm by the energy released by the first energy storage mechanism is balanced, and the first energy storage mechanism cannot release energy and remains in the energy storage state, and cannot immediately drive the separation and closing output crank arm to rotate in the closing direction; at this time, the operator first cancels the driving force on the separation and closing main shaft in the closing direction, and then cancels the first blocking force, breaking the balance of the force acting on the first crank arm end of the separation and closing output crank arm by the energy released by the first energy storage mechanism, and the first energy storage mechanism instantly releases energy to drive the separation and closing output crank arm to perform the closing movement. If the switch is in the closed position, the fuse will be burned out and the ejector mechanism will drive the splitting and combining main shaft to rotate in the opening direction. If a splitting tripping device is provided, the ejector mechanism will drive the splitting tripping plate on the splitting tripping device to rotate, so as to drive the splitting tripping member to rotate, so as to separate the splitting tripping member from the limiting crank arm of the splitting fastener. Under the action of the tripping tension spring, the splitting fastener drives the main shaft crank arm in the reverse direction to drive the splitting and combining main shaft to rotate in the reverse direction. Because the operator has withdrawn the driving force applied to the splitting and combining main shaft in the closing direction before the splitting and combining output crank arm is in the closed position, the ejector mechanism can drive the splitting and combining main shaft to rotate in the opening direction at this time, so as to allow the first energy storage mechanism to store energy and immediately release energy to drive the splitting and combining output crank arm to rotate in the opening direction, so as to realize immediate splitting, disconnect the circuit and improve the safety of the operating system.
[0184] Example 2
[0185] This embodiment provides an operating system, which is different from the operating system in Embodiment 1 in that the structure of the closing and tripping device 10 is different. Specifically:
[0186] The first driving mechanism 102 in the closing release device 10 can be replaced with other structures. For example, the conical plate can be replaced with a conical platform, similar to the structure of the first transition member 3045 in the second driving mechanism 304; or, the first driving member 1022 can be connected to the holding member 101 to directly turn to the closing button to drive the holding member 101 to rotate; or, the first driving mechanism 102 can also be replaced with a meshing structure of a rack and a gear. The gear is fixed on the holding member 101, and the first driving member 1022 is a rack. Just pressing the closing button can drive the holding member 101 to rotate.
[0187] As a variant embodiment, the holding member 101 can also be other eccentric components. For example, the holding member 101 is a cam, and the protruding part of the cam serves as the second eccentric part 1011. Or the holding member 101 can also be other structures, as long as a blocking force is applied to the closing release part 104 to enable the closing release part 104 to switch between the first locked state and the first unlocked state. The holding member 101 can also be omitted, and the first eccentric component can be directly driven to rotate manually to apply a blocking force to the first eccentric component.
[0188] As a further variant embodiment, the first eccentric component may not be an L-shaped or V-shaped bent crank arm. For example, the first eccentric component is a cam, and the protruding part of the cam serves as the first eccentric part 1041. Or the first eccentric component is a straight-shaped crank arm. One end of the crank arm is rotatably arranged on the frame 60, and the other end serves as the first eccentric part 1041. Other positions of the first eccentric component avoiding the first eccentric part 1041 can serve as the first limiting part 1042, and at this time, a force-consuming lever is formed.
[0189] As a variant embodiment, the closing release part 104 can also be other structures. For example, Figure 7 In this case, the rotation direction of the closing and opening output crank arm 201 is in the front and rear direction of the horizontal plane, and the rotation direction of the closing release part 104 is in the horizontal left and right direction. In the first locked state, the closing release part 104 is blocked and abuts against the first crank arm end 2011 of the closing and opening output crank arm 201 to limit the rotation of the closing and opening output crank arm 201; on the contrary, in the first unlocked state, the closing release part 104 rotates until it separates from the first crank arm end 2011 of the closing and opening output crank arm 201.
[0190] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
